An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-1516 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- opencv-contrib-python (PyPI): affected all versions; fixed in 3.3.1.11\n- opencv-contrib-python (PyPI): affected all versions; fixed in 3.3.1.11\n- opencv-contrib-python (PyPI): affected all versions; fixed in 3.3.1.11\n- opencv-python (PyPI): affected all versions; fixed in 3.3.1.11\n- opencv-python (PyPI): affected all versions; fixed in 3.3.1.11\n- opencv-python (PyPI): affected all versions; fixed in 3.3.1.11\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2016-1516/ (Markdown: https://insights.sbomify.com/CVE-2016-1516/index.md)","id":"CVE-2016-1516","markdown":"https://insights.sbomify.com/CVE-2016-1516/index.md","name":"CVE-2016-1516","record":{"aliases":["DEBIAN-CVE-2016-1516","GHSA-cvhw-2593-5j2q","PYSEC-2026-2816","PYSEC-2026-707","UBUNTU-CVE-2016-1516"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenCV computer vision library","requires_auth":"none","summary":"Attackers can execute arbitrary code via a double free vulnerability in the OpenCV computer vision library.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"opencv","vendor":"opencv"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"OpenCV 3.0.0 has a double free issue that allows attackers to execute arbitrary code.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Double Free in OpenCV","id":"CVE-2016-1516","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"use_after_free","year":"2016"},"n_packages":6,"n_references":4,"next":{"headline":"Improper Input Validation in OpenCV","id":"CVE-2016-1517"},"packages":[{"ecosystem":"PyPI","fixed":["3.3.1.11"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":null,"source":"GHSA-cvhw-2593-5j2q"},{"ecosystem":"PyPI","fixed":["3.3.1.11"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":"pkg:pypi/opencv-contrib-python","source":"GHSA-cvhw-2593-5j2q"},{"ecosystem":"PyPI","fixed":["3.3.1.11"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":"pkg:pypi/opencv-contrib-python","source":"PYSEC-2026-707"},{"ecosystem":"PyPI","fixed":["3.3.1.11"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":null,"source":"GHSA-cvhw-2593-5j2q"},{"ecosystem":"PyPI","fixed":["3.3.1.11"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":"pkg:pypi/opencv-python","source":"GHSA-cvhw-2593-5j2q"},{"ecosystem":"PyPI","fixed":["3.3.1.11"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":"pkg:pypi/opencv-python","source":"PYSEC-2026-2816"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2016-1513"},"products":["OpenCV 3.0.0"],"published":"2017-04-10","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code via a double free vulnerability in the OpenCV computer vision library.","url":"https://insights.sbomify.com/CVE-2016-1516/"}
